Symbol comment
|
Derived from Ae. ventricosa. Recessive {667}.
Lr37 can be recognised in seedlings at low temperatures (17oC) and is effective in adult plants under field conditions. See also Sr38 (Reaction to P. graminis) and Yr17 (Reaction to P. striiformis)

Comment
|
A resistance gene analog containing an NBS-LRR R gene sequence was isolated from the Ae. ventricosa segment carrying Lr37 {0183}.
The 2NS translocated segment carrying Lr37 replaced the distal half of chromosome 2A (25-38 cM) from Xcmwg682-2A to XksuH-9-2A. PCR markers were developed for the 2NS and 2AS alleles of Xcmwg682{10073}. SCAR markers SC-372 and SC-385 were developed in {10796}.
